Nathnael 427665f5b2 feat(types): own the currency list in one place ...

PAYMENT_CURRENCIES was copy-pasted into six files — four freight DTOs and
two portal zod schemas — with no owner, and @edr/api-common's exchange
service kept a seventh copy of its own as a bare "USD" | "ETB" union. They
had already drifted: the DTOs and the exchange service did not agree on
what the platform could price in, so a form could offer a currency the
rate service had never heard of.

Adds PAYMENT_CURRENCIES (now including DJF), the PaymentCurrency type and
an isPaymentCurrency guard for the free-string currency columns the ORMs
hand back. Every existing list re-exports this one instead of becoming a
seventh copy.

Also carries the two rules that have to travel with the list:

CURRENCY_DECIMALS, because DJF is a zero-decimal currency — an amount with
centimes is not a more precise payment, it is a malformed one, and CAC
Bank rejects it. roundMoney() applies it.

PROVIDER_CURRENCIES, which gateway settles which currency. Only CBE_BILL
carries a restriction the code can evidence (CBE settles ETB, plan D8);
eBirr, Waafi and D-Money each pass input.currency to the provider verbatim
with an explicit comment saying so. The other rows are therefore
permissive on purpose rather than guessed — settlement currency is really
a property of the merchant account, not the provider brand, and tightening
a row on a hunch would break a live flow.
